13 Claims.

This invention relates to concealed hinges of the type and kind employing superimposed links pivoted to each other and to the housing butt parts at one end, and having sliding connections at the other ends with opposed housing butt parts; and the object of my invention is to provide housing butt parts of the class described formed from sheet material so shaped as to form the various bearings or guide channels of the casing portion, and further so as toreinforce and strengthen said butt parts whilel materially reducing the cost thereof as well as the weight of said parts, and still further in providing longer wearing bearing surfaces; and with these and lliA other objects in View, the invention consists` in a hinge of the class and for the purpose specified, which is simple in construction, eicient in use, and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by reference characters in each of the views, and in which: l

In the manufacture of concealed multiple link hinges wherein each link is composed or" a single metallic body or laminated body, it has been the customary procedure to provide housing butt parts usuallyr formed from die castings. This type of hinge has been found objectionable pri- 45 marily from the standpoint of the vcost of producing the same and alsoy from the standpoint of the weight of the hinge and the wearing properties thereof. It is the purpose of myinventionto construct housing butt parts` of hinges of the` 50` type and kind under consideration from sheet metal rst to materially reduce the cost of these butts; secondly, to lighten the Weight thereof; and thirdly, to produce a stronger butt and one of longer life wear. Still further, in constructing g5. hingebutts of the character describedfromsheet.

(Cl. 163-166) f metal, the shaping of the sheet metal to form the various guides and bearings, automatically produces inthe resulting butt a very strong and sturdy reinforced butt.

Inillustrating one adaptation of the invention, 5 I have shown in Figs. l to 5 inclusive a concealed hinge comprising two housing butt parts I0, Illa, each of which is ofthe same construction, and simply reversed as to position in. coupling the two butts together by a` series of links II, IIa. 10 The links I I are Xedly pivoted to the butt I0 as at I2, whereas the links IIa arev fixedly pivoted to thebutt' Ica as at I 2a.. The links II also'have sliding pivotal mountings I3 in the butt Ilia, e.. whereas the links I I a have sliding pivotal mount- 16 ings I3a in the butt Ill. Thejlinks are ofsthegeneral contour illustrated in plan in Figs. 2 ande ofthe drawing and are pivotally coupled toeach other centrally thereof as seen at I4. This link construction is more or less conventional. It Will 20 also appear that on the sliding pivot pins I3, sleeves I5I are disposed to provide free sliding movement of Kthe pins in channels or guides in the butt Illa, and similar sleeves I5a are employed on the pivot pins I3a.

Each butt I0, Ia, is composed of two sheet metal parts; and as both butts are of identical form, the brief description of one will apply to the other. It will be understood. that the butt Illa is simply reversed to dispose the-parts which 30` are shown on the bottom in the butt I0 in Fig.

5, as vbeing on the top in the butt Illa. One part of each butt comprises a housing or box-shaped part IlV having spaced horizontal bearing Walls Il, and I8, joined at one side in a vertical wall 35 I9, and the front edges of the walls- I'I4 and I8 include laterally extending attaching plate iianges 20, 2I. Both horizontal walls II and I8 are pressed outwardly to form forwardly and backwardly extending grooves or channels 22j and 40 23, respectively, Which terminate short of the flanges lillya 2I. As will be apparent, these channels form reinforcing ribs which extend substantially the full length of the walls Il" and I8:

The walls Il and -I8 areaperturedasseen` at 45 24 to receive the pivots I2, I2a. Itl will appear from a consideration of Figs. 2, 4 and 5, that the vertical wall I9 is shorter in width than the lengthof the walls Ilv and I8 to form-a` space-25 at the attaching plate ends of the part" I6V to 50 receivespaced` cylindrical bearing portionslG onr the companion butt partl Ilia, which is shown detached from the part I6 in Fig. 5 of theV drawmg.

The part IGa comprises substantially a corrugated strip of metal offset to form two long U-shaped or channeled bearing portions 21, 21a between which is a space or channel 28 for receiving one link of the hinge. Outwardly of the bearing 21 or between this bearing and the wall I1 is formed another space or channel 28a for receiving another link of the hinge. The wall portion 29 of the part lIia` which joins the two bearings 21, 21a, has at its outer end one of the cylindrical bearings 26, whereas the wall portion 30 which extends 'from the bearing 21 includes at its forward end the other of the bearings 26, as will clearly appear in Fig. 5 of the drawing. The wall portions 29 and 39 are arranged directly upon the vertical wall I9 and are welded or otherwise secured thereto so that the partJGa becomes an integral part of the part I6 in forming the complete hinge. Y'

It will also appear from a consideration of Fig. 5 of the drawing that the free side edge of the wall I8 of the part I8 includes an upwardly extending flange portion 3I which forms a bearingmember of a width equal to the width of the wall part I9 and adapted to engage or to be arranged in juxtaposition to the adjacentlink; for example the lower link IIa, Fig. 1', and the upper link I I,` Fig. 2. It will also appear that theV outer edges of the horizontal wall portions of the bearings 21, 21a are rounded as seen at 32, note Figs. 2 and 5, to clear the links when the butts are in closed position as seen in Fig. 2.

With the structure as shown in Figs. 1 to 5 inelusiveV it will be apparent that two relatively simple sheet metal parts can be produced in lforming upon the assemblage thereof a strong and durable sheet metal hinge butt, the corrugated formation of the part Ia. adding material strength to the butt while at the same time forming the spaced bearings which guide and reinforce the links of Vthe hinge, as well as in forming bearing surfaces over which the bearing sleeves I5, I5a are free to slide. In this connection it will be understood that the vertical surfaces of the bearings 21, 21a are in alinement with the grooves 22, 23, as is clearly seen in Figs. 2 and 3 of the drawing.

' In Fig'. v6 of the drawing, I have shown for the purpose of illustrating another adaptation of the invention, one butt part made from a single sheetofrnaterial rather than from the twol sheet metal parts as shown in'Fig. 5. Here again, as both'butts'are `of identical form, the brief desc'riptiony of one will apply to both, and for this reason only one butt is shown. The butt part is designated generally by the reference character 33 and comprises substantially similar topI and bottom walls 34, joined at one side by a Vertical wall 'portion 35;` the forward ends of the walls 34 having laterally extending flanges 36. The walls 34 have outwardly pressed channeled p0rtions 31 which are similar in all respects to the channeled portions 22, 23; the walls 34 having apertures 38 similar to the apertures 24 for receiving the fixed pintles of the links of the hinge similar to the pintles I2, I2a.

At 39 is shown the vertically arranged flanged portion equivalent to the flange 3|. present construction, instead of using a separate part such as the part Ilia, the vertical wall 35 is pressed inwardly to form one channeled bearing 4I).` similarv to the bearing 21, whereas the inwardly set wall portion 4I` forms the bearing equivalent tothe bearing 21a. This wall extends downwardly into and partially forms the channel 31. With this construction it will ap- Wth the pear that the bottom wall part 34. of the boxshaped housing extends beyond the inwardly set wall 4I as indicated in dotted lines at 34a, and forms the supportfor the xedpivot pin of the hinge. The forward edges 42 ofthe bearings 40, 4|,.terminate short of the attaching plates 36 of the butt as do the bearings 21, 21a, providing the clearance for the hinged links as will be apparent. The forward edges of the wall 35 or portions thereof above and below the bearing 40 terminate in cylindrical bearings 43 similar to the bearings 26 for receiving the fixed pintle of the hinge. These bearings are in alinement with the apertures 38.

It will be understood that if desired, the entire U-shaped box portion comprising the plates 34,

35 and their associated parts may be contained in a box-shaped shell similar to the parts I1, I8 andA I9, simply to form a uniform box-shaped appearance as well as adding somewhat to the strength of the hinge. However, the use ofv such a housing is not absolutely essential. For this reason, the housing is not indicated. This is also done for sake of clarity in the illustration.

Hinges of the type and kind herein described may be made in slightly different forms of construction andy may be produced in many sizes in adapting the same to different uses. It is desirable, however, in the construction of hinges of this kind to keep limits of the hinge within a more or less rectangular box-shaped contour, particularly with respect to the U-shaped housing part which facilitates the mounting of the butts in connection wtih their supports. It will also be apparent that in some instances, instead of using relatively thick links, links of the laminated construction may be employed. Here again the number of links employed in the respective butts may be Varied and the butt structure varied accordingly to suit different types and kinds of installations.
